Electrochemical properties of Ti/SnO2 anodes, such as oxygen evolution potential, current efficiency and service lifetime, have been enhanced significantly by Nb/Sb co-doping. Characterization of X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) indicated that Nb substituted Sn in SnO2 lattice with the chemical state of Nb5+. Electrochemical impedance spectroscopy (EIS) measurement showed that Ti/Nb-Sb-SnO2 anodes, compared to Ti/Nb-Sb-SnO2 anodes, have a lower charge transfer resistance, exhibiting more efficient electrocatalytic activity. These results suggest that Ti/Nb-Sb-SnO2 anodes are suitable for use in wastewater treatment.
